Résumé

Farmed salmon is a large export product from Norway. After the salmon is stunned and killed, it istransported to large tanks for bleeding, chilling and buffering before gutting and further processing. The temperature of the fish into the processing plant is varying, but it is necessary to cool down the fish fast, both to reduce bacterial growth and to maximize yield. In this paper, the chilling process in salmon specimens are investigated. The temperatures in both salmon and cooling water (RSW) were measured. All the fish was chilled by 1.0 to 3.2 °C during the stay in the tank. There are several possible reasons for the temperature variations. For examples varied the fish temperature into the tank from one test to another, the flow through the processing system varied (mainly because of technical issues in other parts) and the refrigeration system could not always provide RSW at the required temperatures. The main goal is to have more even and larger temperature differences, and to achieve that the focus should first be on the RSW system (both refrigeration system and the water pipes and components) and to ensure that it works properly.
